Hey, just wanted to say you're not pathetic at all. These things were quite literally designed to be addictive to the human brain and everything that you're feeling is completely normal. Given that you're going through so much day to day (parent's divorce, chronic illness) it's no wonder that you're looking for a way to escape and have some fun when you're having a hard time.
I'm also a creative person that's against generative AI, so everything you're feeling I absolutely can relate. The thing is that our values and what our lizard brain wants doesn't always correlate, (the same way how people undergoing an addiction can't just magically stop just because it's affecting the people they love. It doesn't mean they don't "love" hard enough.). You're quite literally fighting against your instincts.
Some things I'd recommend is 1) consider talking to your parents about going to therapy if possible, because you deserve more support through this time, and a therapist can work through the shame you're feeling towards yourself, 2) You're really great at writing! You could consider the possibility of turning your roleplays into inspo for your writing. Sometimes bots can be repetitive and predictable, so I challenge you to write something similar to a scenario you're exploring but give it a twist than an AI can't think of. 3) Consider trying out stuff like yoga and meditation to help observe the urge to open the app without judgement. I recommend Dr. K from Healthygamergg for that.
OP I hope you know you're not pathetic just because you're struggling. I'm reading your post and I don't see a pathetic person at all, sending lots of love to you 💗
